CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of Chinese utility model application No. 201220570545.2 filed on 1 Nov. 2012, the disclosure of which is incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a shower door and, in particular, to a fast mounting structure used for shower doors.

BACKGROUND OF THE INVENTION

Conventional shower doors comprise a stationary frame for fixing to a wall and a movable frame that is capable of adjusting its position in relative to the stationary frame such that both frames are properly engagement with each other. In order to engage both frames, the frames have to be aligned and drilled and fasteners are used to pass through the drilled holes and fasten the frames together. The assembly method of this kind is inconvenient to operation and quite time consuming. In addition, the drilling operation can possibly make damage to the materials made of the frames, for example aluminum materials. This may affect the appearance and service life of the shower door, or even cause the shower door unusable.

SUMMARY OF THE INVENTION

An object of the invention is to provide a shower door assembly which has relatively simple structure and is convenient for assembly, and in particular does not need to be drilled.

Another object of the present invention is to provide a fast assembly method for a shower door which has simplified steps and takes less time.

To achieve the above objects, a shower door assembly is provided which comprises a stationary frame having a guiding groove, and a movable frame having a first engaging element, wherein the shower door assembly further comprises at least one adjusting slider slidably mounted in the guiding groove, the at least one adjusting slider has a second engaging element for engagement with the first engaging element when the movable frame is moved towards the stationary frame, and the shower door assembly further comprises a filler for being disposed in a space formed between the stationary frame and the movable frame when a relative position between both frames are determined.

When the shower door is to be assembled, the adjusting slider is placed into the guiding groove and the movable frame is moved towards the stationary frame. When the relative position between the stationary frame and the movable frame is determined, the first and second engaging elements are engaged with each other . At least one filler is then provided to be inserted between the two frames to press against the two frames such that the first and second engaging elements are in close and immovable contact.

In one embodiment, a through hole is provided on the stationary frame for fixing to a wall or other surfaces by using such as fasteners.

In another embodiment, a third engaging element is provided on the stationary frame for engaging with the filler, so as to prevent the filler from shifting during long term usage.

In another embodiment, the shower door assembly comprises two adjusting sliders each disposed at each end of the stationary frame in order to enhance the stability of the shower door. Of course, the number of adjusting slider can be more than 2, for example 3. However, two adjusting sliders are preferable in view of manufacturing costs and stability.

In another embodiment, the filler has a same length as that of the stationary frame such that the filler can engage with the stationary frame along the whole length of the latter to improve the stability of the shower door.

In another embodiment, a blocker is provided on the stationary frame for preventing the filler from moving towards the wall. The blocker can limit the inserting depth of the filler such that the filler can possibly be taken out when needed in future.

In another embodiment, the first and second engaging elements have inverse teeth to enhance the engagement relationship there between.

In another embodiment, the filler is made from elastic materials and has a larger width than the width of space defined between the stationary frame and the movable frame such that when the filler is inserted into the space it will apply an expanding force against the frames, especially to the engaging elements, so as to ensure the close engagement between the engaging elements.

In another embodiment, the guiding groove is disposed at middle of the width of the stationary frame and spaced from either side of the stationary frame. In this case, two fillers are preferably provided at each space defined by the stationary and movable frames. The guiding groove can also be otherwise located. For example, it can share a sidewall with one sidewall of the stationary frame.

In operation, the stationary frame is firstly fastened to a wall or other surface by using fasteners or adhesives and then at least one adjusting slider is placed in the guiding groove. To engage the two frames, the movable frame is moved towards the stationary frame and when a relative position between both frames is determined, the first and second engaging elements are engaged with each other. The filler is finally inserted between the space defined by the movable frame and the stationary frame to enhance the engagement relationship between the engaging elements.

The present invention has relatively simple structure and is convenient for assembly. In particular, it does not need to be drilled such that the risk of damage is minimized. In addition, a fast assembling method can thus be obtained that has simplified steps and takes less time.
